TRACTION ATTACHMENT FOB VEHICLE-TIRES. I

r Specification of Letters Patent. Application filed April 9.1907. Serial No. 367.272.

Patented Nov. 12, 1907.

-chusetts, have invented certain new and useful Improvements in Traction Attachments for Vehicle- Tires, of which the iollowing is a specification.

This invention relates to removable traction-attachments especially applicable to rubber tires, the general object of such attachments being to prevent My present invention or improvement has for' its principal object to provide an anti-skidding device in whichthe sections are removable without necessitating the employment of tools, and can be returned into position or replaced by others, .or by such removal render the device applicable to tires of different sizes.

' The. nature of the invention is fully described in detail below, and illustrated in the accompanying drawings, in which:

Figure'l is a side elevation of a traction-attachment.

embodying my invention, applied to a tire. Fig.- 2 is a top or plan view oithe same. Fig; 3 is an enlarged view of one of the connecting links removed. Fig. 4 is a cross section of my device applied. to a tire. Fig. 5 represents a slight modification.

Similar letters of reference indicate corresponding 7 parts. 30 v ranged transversely on "the tire at equal distances apart. Each section consists of the main portion or strap 6 constructed of leather or other flexible and 'sufiiciently durable material, rings or loops f secured to opposite ends of said main portions or straps, and

treadsand rivets applied at the central or tread portion of the straps. Each strap is folded as illustrated, whereby its oppositely beveled ends 9 overlap at the centralor tread portion, which is, when the device is in position, on the periphery of the tire, thus providingloops h next the opposite sides of the tire. The central or tread portion of each strap e is flattened and in a straight line by the employment of a rigid,

flatmetallic plate ortread k which is secured to the strap longitudinally (transversely with relation to the ,tirelby headed rivets 1, said rivets not being new in this invention and extending through the plate and i the two looped ends of the strap, securing said ends together-some of said rivets extendingthrough the two folds of the strap on opposite sides of the rigid Woonwonrn, a

tread is. These rivets also constitute anti-friction contact suriacesor feet, and other rivets l may.be employed which do not necessarily extend through both layers of the strap.

The rings f are preferably metallic and circular, and are held by the loops h on opposite sides of the tire, and said rings are connected together in two unbroken series on opposite sides of the tire by links p, preferably metallic, one end of each link being open and formed with inturned ends 1 whereby it may be applied to and connect adjacent rings f.

In order that the device may be easily removed from the tire, two adjacent rings on each side are connected by a strap and buckle s instead of by a metallic link.

It is evideniothat to apply or remove this device is a simple matter, as it requires merely the buckling or unbuckling of the straps 3. Moreover it is compantively easy to render the traction-attachment applicable to tires of greater or less diameter, as all that is necessary is to remove one or more sections by opening the ends of two or more of the links p, or to apply one or more sections by the employment of two or more extra links p. Thus all necessity for the employment of tools in removing or applying the device is obviated.

By means of the'flat metallic treads h and the headed rivets on said treads, the tread of the attachment is broadened, and instead of being in a narrow line is as broad as the distance between the rivets or feet l at the extreme outer ends of the plates k. This of course increases the amount of traction and aids largely in preventing skidding or slipping. Moreover it enables the treads and rivets to wear evenly as otherwise the flexible strap would conform to the curvature of the tire, and the greatest wear would come on the central rivets or points of contact.

In the modification illustrated in Fig. 5, I provide instead of the whole or unbroken rings p split rings t, and the links which connect the split rings may be whole as indicated at u.

It will readily be seen that by properly tightening the buckles s the sections are held firmly in position on the tire without necessity for any straps or other connections extending under the rim.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is:

intermediate 01'. and connecting said rings,tor the purpose set forth.
